Queeny design engineers are able to produce a seals solution for the most basic applications,to those that are extremely complicated and unique. We are able to provide you these solutions supported by life test data and years of excellent field performance.As your partner, we provide sealing solutions for centrifugal pumps,agitators and other rotating equipment, and help you consolidate your brand and market position.

 

Our mechanical seal model 8-1 can Replace AESSEAL M01S and CRANE 8-1,which is widely used for industrial pumps.  The normal material combination include resin carbon/ceramic/NBR/ss304,resin carbon/tc/nbr/ss304,sic/sic/NBR/ss304 ,tc/tc/NBR/ss304 and so on. we also can make changes as customers'requirement or totally design a new type of mechanical seal to meet clients'needs.

Stationary Seats:
1. The standard seat for the TS8-1 seal is the "P" type seat.
2. The A, W, and PP type seats are also available for this seal.
 
Rotary Ring (Carbon/SiC/TC)
Stationary Ring (99%Ceramic/ SiC /TC)
Secondary Seal (NBR/FKM/Encapsulated Ring)
Spring&Other Parts (SUS304/SUS316)
 
Structural Features:
1. The Secondary Seal O-ring material can be specified to allow the seal to be used in various fluids.
2. Applications include all types of rotating equipment, such as centrifugal pumps, mixers, and agitation crushers.
3. Mechanically driven, reducing attrition from the shaft and sleeve.
4. Seal is a multi-spring, unbalanced type that meets API610 standards.
